Default DIY E90 N54 Valve Cover Gasket - 11-27-2012, 10:30 PM

Seems this DIY has never been done but it needs to be. It's really not that hard and the dealer charges $1000+ to do this. Ridiculous.

Disclaimer: I am not responsible for any damage done to your car following this tutorial. Worked perfectly for mine so it should for yours as well.

**Before you begin - DISCONNECT BATTERY! You'll be messing with electricity and fuel - not fun!**

Some have stated the 26 bolts need to be replace, some say it is not necessary. BMW stated it is not a common practice, only if a problem is noticed and 99% of the time it is not needed.

Here are the part#'s (thanks to user "joe-" for part#'s):

7544369 bolts x 26
11127565286 gasket
11127548063 bolts x 3
11127556977 bolts x 2

Torque specs: 7-7.4 lbs

Pic of new Valve Cover Gasket:



Remove passenger Side Cross Bar:





Remove Coils:



Remove O2 Sensors:



Remove clips on Fuel Rail to get access to bolts:



...and remove bolts:



...and remove Fuel Line Fitting (HIGHLY suggest doing this with a cool motor to avoid pressure release issues):



...and take Sensor off end of Fuel Rail:



Remove vaccum lines off of Booster Line:



Remove the six (6) connectors on Fuel Injectors, three (3) nuts & wires on Ground Posts with wires, lastly remove three (3) Ground Posts:



You do NOT need an extra long socket to get Ground Posts out - simply put socket on Ground Post and then socket/rachet halfway in socket hole:



Pry open tab CAREFULLY to get connectors off Fuel Injectors:



Remove fittings on all six (6) Fuel Injectors and remove entire Fuel Rail:





Remove Wire Holder connected to valve cover (by this point all wires, connectors, etc should be disconnected) - Note the blue-headed that BMW says need to be replaced. I disagree



Remove Positive Battery Terminal:



Valve Cover should be able to come off now. Use a putty knife and seperate Valve Cover from Head - do NOT force it or you could crack it. Also, don't gouge the head with any tool you use. I was able to get it loose by just lossening one side:



Cool pics of motor with Valve Cover off - look at that sexy motor LOL:





Get all Gasket material off of Valve Cover and Motor, being careful not to let anything fall into Motor. As you can see below, there's no way this old Valve Cover Gasket was sealing! Had a talk with Rob Beck today regarding this and the gasket not sealing can cause a lot more issues than one might think. The head breathes into the Valve Cover. If the gasket is leaking, it pressurizes your crank case and can cause issues with Turbos, etc. I'll let Rob chime in and elaborate on this.

Use Valvoline chlorine free parts claener applied to the rag not the surface, dont want to much parts cleaner in the motor LOL!!








Clean surface on Motor of all Gasket material - Very important! If you leave it dirty, you will be sorry:



This picture illustrates where the Head breathes into the Valve Cover - have to give Rob Beck credit for this, I had no idea! LOL:



Clean out debris here (I found a bunch of burnt June Bugs in mine! LOL):



New Valve Cover Gasket installed - just push it on:



Insert Spark Plug Guides into Valve Cover before installing it on motor:



Installing Tips:

Really couldn't get pics of this. It's easiest with another pair of hands. Move everything out of the way, the ECU wires go behind Valve Cover easily. Take care not to scrape the Gasket so it falls out. It's really not that difficult - took my wife and I about two minutes to install.

Bolt pattern for tightening I used, I snugged them all then went back and torqued to spec




When putting in bolts, torque down to only 7lbs of torque. Anymore and you will strip the head. Do a bolt pattern - front to back, etc. There's a larger bolt that goes in the right front corner and one that goes in the left rear corner (as you're looking at the car):




TIP: When installing the Fuel Rail, install the bolts first - before you start any fittings otherwise you may strip a bolt hole in the head, like I did (I retapped them easily but much easier if you just don't strip them LOL).




I'd like to send out BIG thanks to Rob Beck for his tips on this job. I appreciate it, man!

Very nice....great job!...thanks, it's DIY's like this that certainly help to bolster one's confidence when taking on projects such as these. Cheers!

One additional note...I read just yesterday where somebody was replacing their valve cover gasket and cracked it by torquing the first bolt prior to "fitting" the others. Just a reminder to progressively tighten all the bolts in a couple iterations instead of all at once.

very good point, I went around 4x. What I did was just snug all bolts on outside in a criss-cross pattern then torqued to spec. Then did the middle bolts. I will add a pic!

If someone is doing the tutorial or just know this answer it would be greatly appreciated!

I forgot wich line goes where (dont think it matters), does the top line on the booster goe to Vaccum canister #1 or #2? I am pretty sure top goes to cannister #1 but would like confirmation.

Awesome pics & text.

I'd like to plug the 6 holes in the head going to the intake ports, tap fittings in the valve cover and install 6 more Oil Catch Cans.

Added a disclaimer that as a preventive you may want to replace bolts, thanks "joe-"" for part#'s.

Also added torque specs!

What are symptoms that this needs to be changed? Just smoke from exhaust at certain times?

Awesome DIY!! One of the best I've seen. Just wishing someone would do something similar for RB's since I'd like to attempt them myself early next year.

Thank you for all the tip! It is the small things like the holes in the head ect that really make the difference and allow us to understand what is going on you really made it simple to understand!

Whew, doing this now.
I couldn't find my shorter extension or my wobble socket. Makes things much easier in the back corner.
My old gasket didn't look too bad. It came out in one piece, even after getting it caught and tugging.

Actually, back corner is easy....use a 8-10" extension and lay it right on the edge of the ECU cover ( where it dips in) and you put the socket and extension on the bolt then attach the ratchet

I did try that and removing the rubber seal around the cowl made all the difference for me in making it fit on there right.
